The migrating mediators and the interaction associated with the use of essential public health services: a cross-sectional study in Chinese older migrants.

BACKGROUND Despite the incremental implementation of the essential public health services (EPHS) during the last decade, the goal of EPHS's equalization is impossible to cannot be achieved without appropriate policies targeting older migrants. Therefore, this study aims to examine whether the supply side meets the needs of older migrants and to explore the relationships among health status, the use of health services, and diverse factors. METHODS The data were derived from a national cross-sectional dataset (N = 11,161) of the 2015 Chinese Migrant Dynamic Monitoring Survey. Mediating effects analysis and moderating effects analysis were conducted to explore the interactions between physical status and the use of EPHS in older migrants such as physical examination, health record, and follow-up services. RESULTS The use of physical examination, health record, and follow-up services were correlated with each other. Household income, migrating for employment, and migrating for offspring were negatively associated with the use of EPHS. A positive association was observed between the use of EPHS and willingness for long-stay. The mediating effects of household income, migrating for employment, migrating for offspring, and willingness for long-stay were observed on the relationship between physical status and the use of EPHS. The moderating effects of household income and migrating for employment were discovered. CONCLUSION Public health policies that may be worthy of consideration include further enhancing the delivery capacity of primary health institutions, integrating professional clinical resources into the primary health system, and launching the target policies to improve the accessibility of EPHS in older migrants.
